A Quote by Martin Rees
Some global hazards are insidious. They stem from pressure on energy supplies, food, water and other natural resources. And they will be aggravated as the population rises to a projected nine billion by mid-century, and by the effects of climate change. An 'ecological shock' could irreversibly degrade our environment.

Devastation could arise insidiously, rather than suddenly, through unsustainable pressure on energy supplies, food, water and other natural resources. Indeed, these pressures are the prime 'threats without enemies' that confront us.
The U.N.'s current projection is that humanity will number 9.3 billion individuals in 2050 and then hit 10.1 billion by 2100. Meanwhile, our energy resources are dwindling, and droughts threaten our food supplies.
City farming is not only possible, it is the very definition of the kind of meaningful, sustainable innovation we will need to meet the grand challenges of the 21st century: climate change; population growth; ageing population; urbanization; rising demand for energy, food and water; poverty; and access to healthcare.
The cost of our success is the exhaustion of natural resources, leading to energy crises, climate change, pollution, and the destruction of our habitat. If you exhaust natural resources, there will be nothing left for your children. If we continue in the same direction, humankind is headed for some frightful ordeals, if not extinction.
Egypt's priorities in fact are all related to the environment: food, water, health, energy, employment and education. Egypt is facing some very serious environmental challenges. The country has limited natural resources and has to decide how to manage these to meet the needs of a growing population.
We need the humbleness and clarity to see that our food, while benefitting from technological advances, has benefitted even more from free ecological resources: Cheap energy, lots of water everywhere, and a stable climate.
Everything we think about regarding sustainability - from energy to agriculture to manufacturing to population - has a water footprint. Almost all of the water on Earth is salt water, and the remaining freshwater supplies are split between agricultural use and human use - as well as maintaining the existing natural environment.
We're facing growing climate change, more floods, more droughts, more crisis on a planetary level, and the systems we put in place in the twentieth century are just not going to work. We've run out of stuff. Our big problems are going to be energy supplies and food supplies. This is not a right-left issue.
By 2030 the demand for resources will create a crisis with dire consequences. Demand for food and energy will jump 50% by 2030 and for fresh water by 30%, as the population tops 8.3 billion
To be clear, climate change is a true 800 pound gorilla in the room. The effects of global warming threaten global environmental upheaval over the coming century. But for South Florida and the Everglades, it could be our death knell if urgent action is not taken.
We're facing growing climate change, more floods, more droughts, more crisis on a planetary level, and the systems we put in place in the twentieth century are just not going to work. We've run out of stuff. Our big problems are going to be energy supplies and food supplies. This is not a right-left issue. It's a people issue, and it cuts across all our categories.
How we grow food has enormous effects on the environment - climate change as well as pollution of air, water, and soil.
With the growth of the world population, the global climate change and the need for a greater healthy environment, access to water resources has become a crucial condition for the realization of an equitable international order, where the needs of the peoples are effectively addressed. In this regard, the need for international cooperation, including in joint effort with relevant non-state actors, is paramount to ensure water is made available to all without discrimination. Water is a human right, an enabling right, not a mere commodity.
Environmental science is telling us a lot about our future and what it could look like, whether we're talking about global warming (the current poster child for the environment) or a loss of genetic diversity in our food supplies, or the effects of low-dose chemicals on human development.
Climate change and energy use are global problems - News Corp is a global company. Our operations affect the environment all over the world.
If we do not change our negative habits toward climate change, we can count on worldwide disruptions in food production, resulting in mass migration, refugee crises and increased conflict over scarce natural resources like water and farm land. This is a recipe for major security problems.
